IPC: G06F3/046
Filed: 1996-12-05
Abstract: PROBLEM TO BE SOLVED: To provide a coordinate input device with less power consumption by lighting a light emitting element between a current source and a loop coil by a current made to flow from the current source to the loop coil. SOLUTION: The current generated in the current source 1 is passed through the light emitting element 3, passed through a transmission/reception switching circuit 6 and made to flow to the loop coil 5 selected by a coil switching circuit 7 and an alternate magnetic field is radiated. In this case, since the light emitting element 3 is made to emit light by the current required for generating the alternate magnetic field in the loop coil 5, another special power source is not required.  For instance, in the case of using a light emitting diode as the light emitting element 3, the current of about 10mA is required, and in this case, since the light is emitted by the current made to flow to the loop coil 5 originally required for achieving a function as this coordinate input device without the need of a special power source, the current of about 10mA, that is the power consumption, is saved.
